The transfer window may be closed and much of the uncertainty and speculation over the futures of many players will come to an end.

However, for a number of Premier League managers the disruption could continue as they deal with the aftermath of what has been a disruptive experience for a number of players.

Managers now must find a way of reintegrating key players who had expressed a desire to move on but now find themselves in limbo after the summer transfer window closed on Thursday night.

Southampton must discover an answer to the Virgil van Dijk problem after the Dutchman was left out in the cold following his public efforts to move to Liverpool.

Shakespeare has couple of deadline day hangovers

Chelsea still have a problematic Diego Costa on their books, although the striker won’t be a disruptive influence while he remains in Brazil, while Liverpool boss Jurgen Klopp must try to bring Philippe Coutinho back into the fold.

Leicester City manager Craig Shakespeare may not have the problems of some of his rivals, but he still has a couple of issues to address as a hangover from the transfer window.

Firstly, England under-21 manager Aidy Boothroyd has stated he felt Demarai Gray had been affected by the uncertainty over his future, when Bournemouth bid £25million for him, and he left him on the substitutes’ bench in Holland.

Shakespeare has to settle the precocious young talent down and get him focused on his football again. The fact City were determined to keep hold of him should convince him how much he is wanted and that his opportunities will come in time.

Gray’s representatives have opened talks over a new contract. The sooner he settles his future by signing it the better for all concerned.

Then there is Riyad Mahrez. He has not kept it a secret that he wanted to leave the club during the window, but City did not entertain offers from Roma, including the final bid of £32m.

Even Mahrez’s desperate flight back to Europe after leaving his Algerian training camp and missing a key World Cup qualifier did not bring about his desired move.

To his credit, Mahrez has not demonstrated that his wish to leave will affect his professionalism.

Shakespeare has stated repeatedly that if he allowed his standards to drop or sulked in any way he would not be included.

No reason to question Mahrez's commitment

Team-mate Andy King also warned his team-mates would not accept such a decline in his standards either.

Mahrez hasn’t given anyone reason to question his commitment so far but now the window is shut and his immediate future is settled it is time for him to refocus for his own, and the club’s, benefit.

Mahrez has been poorly advised. The public statement of his intent to leave so early in the summer was a mistake.

It may have been a ‘come and get me’ cry, but it also risked alienating him from his team-mates and the City fans. Then there was the flight back to Europe on deadline day.

No club was actually in for him at the time but, understandably, not wishing to be stuck on a 10-hour flight to Zambia and therefore out of the loop if a club did come calling, he made the pilgrimage to be closer to the expected action.

However, there was something sad about a player of his standing and talent being sat in an airport waiting for a call that didn’t come, like the last person at a Prom to be asked to dance.

Now is a time for reflection for Mahrez. Someone must have told him that the offers would come, that the big clubs would make a move. Now he has to ask himself why they didn’t and what he has to do now to ensure that they do in the future?

Mahrez needs to impress his boss

The only way he can answer those conundrums is by returning to the match-winner he has been for City in the past.

He has to produce this season and show those potential suitors reluctant so far to meet City’s asking price, that his incredible displays during the title season, performances that earned him the PFA player of the year award and a Ballon d’Or nomination, were not a fluke. That he wasn’t a one season wonder.

Mahrez may have been left helpless on transfer deadline day as he constantly browsed the duty free, but he can help himself and his future now, by going out and doing what he does best; winning matches with moments of individual brilliance and thrilling us all.

Shakespeare must impress on him that the only answer is total and utter commitment between now and January.
